Because of the importance of employee commitment to the success of the changes, this study aims to analyze the relation of the perception of organizational support in its unifactorial and multifactor forms with the components of commitment to the organizational change. The data collected in a sample of 126 workers of a company of large energy and students of the Masters Course PUC, both of Rio de Janeiro, revealed that there is relationship between the three components of commitment to organizational change and the perception of organizational support unifatorial form, but the relationship is not significant for all components when the perception of organizational support is divided into more than one factor (ascension, promotion and payment, polices, performance management, workload and material support).
